Specification of Letters Patent.

Patented Oct. 21,1913.

Application filed February 26, 1906. 7 Serial No. 302,889.

To all whom it may concern Be it known that 137.6,MAXlliHi- IAN CHARLES SGHWEINERT, residing in West Hoboken', in the county of Hudson and State of New Jersey, and HENRY P. KnAr'r, residing in the borough of Brooklyn, county of Kings, city and State of New York, citizens of the United States, have invented certain new and useful Improvements in Water-Bottle Stoppers, of which the following is a specification. v

This invention relates to water bottle stoppers or similar, devices, and aims to provide certain improvements therein.

Our invention is especially applicable to that type of stopper in which the valve seat is formed at the lower end of the socket member, the latter being entended upwardly a considerable distance above the point of its connection with the neck of the bottle, and being provided with suitable ports for the entrance and discharge of water. In this construction of stopper the part which constitutes the stopper proper need not be removed from the socket when the bottle is to be filled or emptied, it being only necessary to screw it upwardly until it passes the ports of the socket member.

Notwithstanding the fact that it is not necessary to remove the stopper from its socket, this is often accidentally done in the operation of filling or emptying, with the result that the stopper frequently becomes lost or misplaced.

Our invention aims to provide a construction in which such accidental separation is impossible, and in which there is no liability of loss of any of the parts.

Our invention also includes certain other features of improvement which will be hereinafter specified.

In the drawings which illustrate certain embodiments of our invention, Figure 1 is a vertical section of the neck and funnel of a hot water bag showing our improved con struction of stopper applied thereto; Fig. 2 is a view of the stopper and retaining cap detached, the stopper being shown in elevation and the cap in vertical section; 3 is a view showing the method of uniting the cap and stopper. 4: and 5 are detail views illustrating the locking means for the cap, Fig. at being in section and Fig. 5 in elevation. Fig. 6, is a sectional viewof a modification.

In the drawings let A designate a hot water bag of any suitable construction having a neck a and a: flaring mouth or funnel.

The socket member B of the stopper is shown as formed of a sheet metal tube having at its lower end an inturned flange 0 adapted to form a valve seat, and having its section f being formed with screw threads to engage those of the socket member B. The section f carries on its lower face a disk 9 of packin material designed to close the opening in the seat 0 when the stopper is in its lower position.

To prevent the withdrawal of the stopper from the socket we provide a retaining device which is preferably adapted to be connected to the upper end of the socket member and to engage a suitable shoulder or pr0- jection upon the stopper. Such retaining device may be constructed in various ways, but in the drawing we have shown the form we prefer to employ which comprises a cap 1) having a vertical flange h which is screw threaded to engage the upper end of the socket member, and a horizontal flange i which is adapted to engage a shoulder j formed at the upper end ofthe screwthrea ded section f of the stopper. The flange 1' extends inwardly a suflicient distance to render it impossible to remove the stopper by working the screw-threaded portion thereof throng the opening inthe flange.

According to our invention we form the cap D (orother similar device) as an inseparable part of the stopper C, so that the cap cannot be lost or mislaid. In the construction shown the stopper is provided with a handle E which is preferably of greater width than the diameter of the opening in the capv D, so that while the-cap may freely move along the section 6 of the stopper it is prevented from slipping off the outer end t reo by h ha d e E- lOO The cap I) may be applied to the stopper in various ways, for instance, by forming it in its completed shape as shown in Fig. l and slipping it over the section 6 either before the handle is connected therewith, or after the handle is applied and before the section 0 is united to the section Preferably, however, we adopt the method. illustrated in F 2 and 0, wherein the parts are shown before and just after the application of the cap to the stopper. According to this method we initially construct the cap D in the form of a screwthreaded tubular section, and preferably give the upper part of the cap D which afterward forum the flange 2' a preliminary bending such as shown in Fig. 2 This bending operation restricts the efiective opening through the cap so that the latter will just pass through the screw-threaded portion of the stopper. J'Vhen the cap has been placed in position on the stopper, the flange 2' is then bent inwardly by a suitable tool. to such extent that its opening is so restricted to render separation impossible. This operation is indicated in Fig. 3, the original position of the flange being shown in. dotted lines. By this method the stopper may be completely formed with its handle riveted to its body, and the whole given the usual coating of nickel plate, before the application of the cap D. The latter also may be plated in the form shown in Fig. 2, and in this condition applied to the stopper and its flange 2' afterward bent to proper position without perceptibly marring the finish of the cap. Tl is mode of application hence has a considerable advant in practice over those hereinabove refei red to.

Our invention also provides an important feature of improvement in connection with the mode of connection of the cap to the socket member. Ordinarily a plain screwthreaded connection is sufficient to securely hold the cap in place on the socket member. It is possible if the cap is carelessly applied by the user, that it may not be screwed firmly enough in place to resist the unscrewing action which the stopper exerts upon it after the stopper contacts with the cap. To obviate the possibility of such accidental unscrewing. we provide a lock for the cap which, while it prevents any unintentional dislodgement of the cap, still permits its intentional separation from the socket member by hand when necessary or desirable as for instance, for inspecting or replacing the disk he construction which we prefer to provide for this purpose is illustrated. in detail in Figs. l and 6. As shown, the upper wall of the socket member is cut to form a spring tongue m, the outer end of which is bent outwardly so that it projects slightly beyond the wall of such member as indicated at n. The cap I) is provided with a recess or hole 0, which when the up is screwed home engages the projection 77., the tongue at springing inwardly a sufficient extent to permit such engagement. When the stopper is in its upper position, however, i s illustrated in Fig. 1, it prevents the inward movement of the tongue m and. hence prevents disengagement of the recess 0 from the projection 72. As it is only when the stopper is in the position of Fig. I that there is any tendency to unscrew the cap it will be observed that the latter is firmly held in position against accidental displacement. If it is desired to remove the stopper, the latter is screwed downwardly until its screw-threaded portion passes from behind the tongue m so that the latter is free to spring inwardly, at which time the application of sufficient force to the cap will cause the recess to become disengaged from the projection. The latter is preferably formed with inclined surfaces to facilitate such disengagement.

Our invention also provides certain improvements in the construction of the stopper proper. In stoppers of the general coi'istruction illustrated in Fig. 1 the stopper proper must be elongated to a considerably greater extent than that ordinarily nece my in order to provide for the greater degree of movement which is required. In the particular construction shown in Fig. l the sections 6 and f are separately formed and united to each other by soldering. This method of connection is comparatively costly and results in a less secure union than is sometimes desirable. By our present invention we obviate this difficulty and produce an extremely strong construction of stopper which may be very cheaply manufactured. As shown in Fig. 6 we form one of the parts as c with an outwardly extending flange 7), and the other of the parts as f with an outwardly and upwardly extending flange Q the parts being united in this condition and the upper part of the flange 1 (shown in dotted lines) being subsequently bent over upon the flange 79 by a suitable tool. This connection affords an extremely strong and r1 gld union between the parts.

While we may so form the flanges 7) and that they do not extend be yond the section f in the finished stopper, we prefer to form them in the manner shown so that the stopper when completed is provided with an annular flange such as illustrated. This flange forms an efficient shoulder or projection for engagement with the cap I). When this construction is adopted the socket member B is provided with an enlarged. portion a which is designed. to receive the flange thus formed. In this construction the mode of application of the cap to the stopper may be that before described, a sufficiently large opening being left in the cap in this instance to pass over the flange of the stopper.

It will be observed that by our invention we provide a stopper having a retaining cap inseparably connected thereto under all conditions of use, so that it is impossible for the cap to become lost or misplaced apart from the stopper. It will also be observed that the stopper is firmly held within its socket so that it cannot be worked out of the cap either accidentally or intentionally and that the cap is securely locked on the socket mem- I her so that it cannot be separated therefrom unless itis the intention to do so, and then only by a special mode of manipulation. It will also be observed that our invention provides an extremely strong and cheap form of stopper, and a novel form of socket member which is especially adapted for use in con nection therewith.

Although we have described in detail certain embodiments of our invention, we do not wish to be limited thereto, as various modifications may be made therein without departing from our invention.
